Application filed February 28, 1906. Serial No. 247.830-

To all whom it may concern.-

Be it known that'I, AMos CALLEsoN, a citizen of the United States, residing in Brooklyn, Kings county, State of New York, have invented certain new and useful Improvements in Caps for Bottles and Jars; and I do hereby declare the followin to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany: ing drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention is an improvement in the metal cap for bottles and jars set forth in United States Letters Patent No. 708,528 to C. 'A. Calleson. Its object is to provide a cap which, except for the usual cor or other lining-pad, Will be a one-piece article and which in the blank will be of symmetrical plain circular shape without projections, so that the minimum waste of metal is incurred in the making thereof, and in its ultimate form will have ample strength in all its parts to resist influences tending to make it release its intended hold on the bottle or jar and produce leakage and yet permit of ready manipulation to accomplish its release when in the manner contemplated this is to be effected'.

In carrying out my invention the, cap is formed by striking up a sheet-metal disk and forming in the flange thus produced, either before or after this, tongues having their bases disposed adjacent the edge of the flan e and lying themselves substantially wholly within the flange.

My invention consists in the combination of a bottle, jar, or the like having an annular bead or collar on the neck thereof and a metal cap fitted over the bottle-mouth and consisting of a single circular piece of sheet metal shaped to form a plain imperforate diskshaped top portion and a depending flange, said flange having the edge portion thereof bent or crimped in under, and thus standing in looking engagement with said bead or collar, and said flange also having therein a weakening which abuts on the inbent edge portion of said flange and extends up close to the plane of said top portion and is restricted in width at at least its upper extremity, whereby while said flange is severable at said weakenin the strength of the ca is retained to resist t e tendency of interna pressure to find escape at a point adjacent the top portion of said weakening.

My invention further consists in the combination of a bottle, jar, or the like having an annular bead or collar on the neck-thereof and a metal cap fitted over the mouth ofsaid bottle and consisting of a single circular piece of sheet metal shaped to form a plain imperforate disk-shaped top portion and a depending flange, said flange having the edge portion thereof bent or crimped inwardly under, and thus standing in looking engagement with said bead or collar, and said flange also having a tongue or tongues formed therein with the base or bases thereof abutting on g view of a cap made from the blank shown in Fig. 1; Fig. 3, a side view, like Fig. 2, except that the cap is shown as turned through a quarter-revolution Fig. 4, a side view showing the cap in place on a bottle; Fig. 5, a view similar to Fig. 4 after the tongues have been broken away and showing the cap partly in section, and Fig. 6 the cap in side elevation after its removal from the bottle.

In the drawings, Fig. 1, a is a disk of sheet metal. I) is the circular concentric line on which the disk is bent to form a flange c and the top or body (1 of the cap 6, shown in the other figures of the drawings.

Before or after converting the blank into the cap a tongue or tongues f are cutout in what is the flange portion 0 the cap. The cut g, which results in a tongue f, is in the adaptation shown preferably of U shape and lies preferably wholly within the flange. As shown in the drawings, there are but two of these tongues, the same being diametrically disposed for a reason hereinafter explained; but I do not wish to be limited to the number thereof.

The cuts 9 have their ends disposed adjacent the edge of the flange. The consequence of this is that the base of the tongue Is also disposed adjacent said edge of the flange. As shown, the extremities of the tongues project upwardly; but that is not essential in every respect of my invention.

. crimped lnw ardly under Upon being assembled with a bottle or jar the edge portion h of the flange is bent or the surrounding bead or collar 7'. on the bottle'or jar neck, interlocking securely therewith, and thereby both preventing removal thereof except in the manner intended and loosening and consequent leakage. In this connection it should be remarked that it is preferable to employ the usual lining disk or pad of cork or the like fitted into the ca to insure the hermetic character of the seal The extremities of the tongues are preferably left projecting a little from the flange. (See Fig. 3.) Therefore when it is desired to remove the cap from the bottle the tongues are readily bent downwardly, (see dotted line, Fig. 3,) so as to break the continuity of the flange,whe re it was originally left intact in its edge portion on forming the tongues, and thereby destroy the interlocking engagement of the bottle and cap. In the adaptations shown the hold of the inbent or crimped edge portion h of the flange on the collar or bea 'L of the bottle may be broken by bending the cap on a line extending diametrically across its body or top (1. (See Fig. 6.) j is a cut formed in the-edge of the flange opposite each tongue, its purpose being to further weaken the flange, so as to facilitate the breaking out of the tongue in the manner above described.

The forming of the cut g wholly within the flange and the further fact that its uppermost end is restricted in width (by being inverted- U shaped, for instance, in the form shown) has the following very important advantage, to wit: The flange is weakened upwardly far enough so that it may be bent diametrically across the top (1 in line with the cut and in the manner above described, whereby to make its inbent edge portion clear the bead on the bottle-neck, and yet internal pressure cannot bulge up the top at immediately over the cut, affording leaka e, because the cut only has restricted widtfli at its uppermost end, and so arching of the top (1 directly over said out is prevented.

Having thus fully described my invention, 7

what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a bottle, jar or the like having an annular bead or collar on its neck, and a metal cap fitted over the mouth thereof and consisting of a single circular piece of sheet metal shaped to form a plain lmperforate disk-shaped top portion and a depending flange, said flange having the edge iece of sheet metal s portion thereof bent in under said bead or collar and thereby locking said cap to the bottle, and said flange also having a weakening extending approximately from its inbent edge portion up to approximately its top portion and said weakening being of restricted width at its uppermost end, substantially as described.

2. The combinationof a bottle, jar or the like having an annular bead or collar on its neck, and a metal cap fitted over the mouth thereof and consisting of a single circular aped to'form a plain lm'perforate diskshaped top' portion and a dependin flan e, said flange having the edge portion thereof bent in under said bead or collar and thereby locking said cap to the bottle, and said flange also having a cut extending approximately from its inbent edge portion up to approximately its top ortion and said out being of restricted width at its uppermost end, substantially as described.

3. The combination of a bottle, jar or the like having an annular bead or collar on its neck, and a metal cap fitted over the mouth thereof and consistin of a single circular piece of sheet metal shaped to form a plain lmperforate disk-shaped top portion and a dependin flan e, said flange having the edge portion t ereof bent in under said bead or collar and thereby locking said cap to the bottle, and said flange also having a tongue formed therein with 1ts base abutting on the inbent edge portion of said flange, substantially as described.

4. The combination of a bottle, jar or the like having an annular bead or collar on its neck, and a metal cap fitted over the mouth thereof and consistin of a single circular piece of sheet metal sflaped to form a plain imperforate disk-shaped top portion and a depending flan e, said flange havin the edge portion thereof bent in under sai bead or collar and thereby locking said cap to the bottle, and said flange also havinga tongue formed therein by a cut penetrating the flange and having its ends abutting on the inbent edge portion of said flange, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 24th day of February, 1905.

AMOS CALLESON.
